The problem comes when someone has already downloaded a previous version of your map. Perhaps, at the time, a past version was the most recent. In this case, anyone who downloaded the map over 20 days ago from here will get a version mismatch any time they attempt to join a server with the most recent version. Alternatively, a server running an older version of the map will also get version mismatches, and they might not even realize it because they can't easily tell what version they have. All for what? So the map name looks slightly prettier? Saying people should only download it from Steam is a poor excuse for a problem that can be so easily fixed by just renaming the file. We have these naming conventions for a reason. We're not Valve; we can't force everyone to download the same version of our map.
